Tips
- Diagnosing: Typically you can tell a front bearing is going out if after a run there is a large wet spot on the bottom of your motor next to the flywheel. A little bit of wet is ok and usually just a sign of a rich low-end needle. If the bearing is bad your risks/issues will be inconsistent tune and possible chance of damaging the crank/case if it completely goes.
- Installation: The best way to install is to use a bearing puller/installer, OFNA makes a very affordable one. If you place the new bearing in the freezer for 15 minutes it will be easier to install.
- Positioning: This is a single rubber sealed bearing to allow for proper lubrication. Place the rubber seal towards the outside (facing clutch).
- Break-In: For the first run of these bearings, Avid suggests that you fatten your motor up on the high-end needle so the ceramic balls will seat instead of skidding them.
